Doubts over Ballack, Carvalho

Jose Mourinho could be without injured defender Ricardo Carvalho and midfielder Michael Ballack for the Champions League semi-final first leg tie against Liverpool at Stamford Bridge tomorrow.

Carvalho missed the draw at Newcastle with a leg injury while Ballack was forced out of the action in the same Barclays Premiership game with an ankle problem.

Midfielder Michael Essien is suspended and winger Arjen Robben is also out with a knee injury.

Provisional squad: Cech, Cudicini, Hilario, Ferreira, Geremi, Diarra, Terry, Boulahrouz, A Cole, Bridge, Makelele, Essien, Mikel, Lampard, Drogba, Shevchenko, Kalou, Wright-Phillips, J Cole.
